  • Electronically Excited States of Closed-Shell, Cyano-Functionalized Polycyclic Aromatic Hydrocarbon Anions
    Article Electronically Excited States of Closed-Shell, Cyano-Functionalized Polycyclic Aromatic Hydrocarbon Anions Taylor J. Santaloci and Ryan C. Fortenberry * Department of Chemistry & Biochemistry, University of Mississippi, University, MS 38677-1848, USA; [email protected] * Correspondence: [email protected] Abstract: Few anions exhibit electronically excited states, and, if they do, the one or two possi- ble excitations typically transpire beyond the visible spectrum into the near-infrared. These few, red-shifted electronic absorption features make anions tantalizing candidates as carriers of the dif- fuse interstellar bands (DIBs), a series of mostly unknown, astronomically ubiquitous absorption features documented for over a century. The recent interstellar detection of benzonitrile implies that cyano-functionalized polycyclic aromatic hydrocarbon (PAH) anions may be present in space. The presently reported quantum chemical work explores the electronic properties of deprotonated benzene, naphthalene, and anthracene anions functionalized with a single cyano group. Both the absorption and emission properties of the electronically excited states are explored. The findings show that the larger anions absorption and emission energies possess both valence and dipole bound excitations in the 450–900 nm range with oscillator strengths for both types of >1 × 10−4. The valence and dipole bound excited state transitions will produce slightly altered substructure from one another making them appear to originate with different molecules. The known interstellar presence of related molecules, the two differing natures of the excited states for each, and the wavelength range of peaks for these cyano-functionalized PAH anions are coincident with DIB properties. Finally, the methods Citation: Santaloci, T.J.; Fortenberry, utilized appear to be able to predict the presence of dipole-bound excited states to within a 1.0 meV R.C.

  • Application of a Hydrogenation Catalyst Modified by Formaldehyde
    Application of a hydrogenation catalyst modified by formaldehyde O. G. Degischer1, R. Novi1,2, F. Roessler2, P. Rys1 1ETH Zurich Hoenggerberg, 8093 Zurich, Switzerland. 2Roche Vitamines Ltd, Bldg 214 Room 8, 4303 Kaiseraugst, Switzerland. Introduction The hydrogenation of nitriles is an important method for the industrial production of primary amines. Normally, the product mixture contains primary, secondary and tertiary amines, as well as traces of amides and alcohols. A general reaction scheme for the hydrogenation of nitriles to the primary and secondary amines is shown in figure 1. The selectivity of the nitrile hydrogenation depends on several factors: the nature of the individual catalyst, the solvent and additives such as ammonia, alkali hydroxides, etc. In addition, the selectivity can also be influenced by conditions such as pressure and temperature. A recently published patent1 describes the modification of Raney catalysts with formaldehyde. Compared to reactions with unmodified catalysts, those run with catalysts modified by formaldehyde show an increased selectivity in favour of the formation of primary amines.

Results and discussion The hydrogenation of aromatic nitriles was investigated using commercial Raney nickel catalysts, either unmodified or modified by formaldehyde, with benzonitrile as a model compound and methanol as the solvent. After the modification with formaldehyde the activity of the catalyst decreases, whereas the selectivity towards primary amine formation increases, both in the absence as well as the presence of ammonia (table 1).

  • Abstract Cold and Dense Samples of Naphthalene (C10H8) Are Produced
    Abstract Cold and dense samples of naphthalene (C10H8) are produced using bu®er gas cooling in combination with rapid, high flow molecule injection. The observed naphthalene density is n ¼ 1011 cm¡3 over a volume of a few cm3 at a temperature of 6 K. We observe naphthalene-naphthalene collisions through two-body loss of naphthalene with a loss cross section ¡14 2 of σN ¡N = 1:4£10 cm . Analysis is presented that indicates that this combination of techniques will be applicable to many comparably sized molecules. This technique can also be combined with cryogenic beam methods 1 to produce cold, high flux, continuous molecular beams. 1 Cooling and Collisions of Large Gas Phase Molecules David Patterson, Edem Tsikata, and John M. Doyle February 5, 2010 1 Introduction Driven by a variety of new science, including cold chemistry and dipolar quan- tum gases, several methods are now being pursued to produce cold and ultracold samples of molecules. The cold molecules in these studies are generally diatomic 2 but also include few-atom molecules such as ND3. Extending this work to the cooling of larger molecules is of high interest, as reviewed by Meijer et. al. 3 and references therein. For example, chemical reaction rates at low temperatures are of great current interest, and extending these studies to important large molecules is essential. Similarly, ultraprecise spectroscopy applications could make use of new continuous cryogenic molecular beams. Finally, there is great interest in ¯eld mediated chemistry, and a general source of high density, highly polarizable ground state molecules is an excellent testbed for observing ¯eld mediated chemical reactions.

While the most advanced technological means to photograph and reproduce this document have been used, the quality is heavily dependent upon the quality of the original submitted. The following explanation of techniques is provided to help you understand markings or patterns which may appear on this reproduction. 1. The sign or "target" for pages apparently lacking from the document photographed is "Missing Page(s)". If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting thru an image and duplicating adjacent pages to insure you complete continuity. 2. When an image on the film is obliterated with a large round black mark, it is an indication that the photographer suspected that the copy may have moved during exposure and thus cause a blurred image.

Density Functional Studies on the Complexation and Spectroscopy of Uranyl Ligated with Acetonitrile and Acetone Derivatives Abstract The oorc dination of nitrile (acetonitrile, propionitrile, and benzonitrile) and carbonyl (formaldehyde, acetaldehyde, and acetone) ligands to the uranyl dication (UO22+) has been examined using density functional theory (DFT) utilizing relativistic effective core potentials (RECPs). Complexes containing up to six ligands have been modeled in the gas phase for all ligands except formaldehyde, for which no minimum could be found. A comparison of relative binding energies indicates that 5-coordinate complexes are predominant, while 6-coordinate complexes involving propionitrile and acetone ligands might be possible. Additionally, the relative binding energy and the weakening of the uranyl bond is related to the size of the ligand, and in general, nitriles bind more strongly to uranyl than carbonyls.

  • A Slow, Continuous Beam of Cold Benzonitrile
    PCCP View Article Online PAPER View Journal A slow, continuous beam of cold benzonitrile Cite this: DOI: 10.1039/c4cp03818e David Patterson* and John M. Doyle A cold, continuous, high flux beam of benzonitrile has been created via buffer gas cooling. The beam has a typical forward velocity of 67 Æ 5msÀ1, a velocity spread of Æ30 m sÀ1 and a typical flux of 1015 molecules sÀ1,measuredvia microwave spectroscopy. This beam represents the slowest demonstrated Received 26th August 2014, forward velocity for any cold beam of medium sized (45 atoms) polyatomic molecules produced to date, Accepted 30th December 2014 demonstrating a new source for high resolution spectroscopy. The expected resolution of a spectrometer DOI: 10.1039/c4cp03818e based on such beams exceeds current instrument-limited resolution by almost an order of magnitude. This source also provides an attractive starting point for further spatial manipulation of such molecules, including www.rsc.org/pccp eventual trapping. 1.
